Question

​What will happen if the person in our example, who picks up balls from below and puts it on top of the C-shaped tube, stops doing his job?

• A. The flow of the current will be stopped.
• B. Even if the person stops working, the current will be there.
• C. The balls will start travelling backwards.
• D. There will be a very high flow of current.

Answer 1

The correct option is A

The flow of the current will be stopped.

The balls move to fill the 'gap' created by a person when he picks one up from the bottom. If the person stops doing his job, the current will stop flowing as there would be no more 'gap' to fill and hence, the balls would remain stationary.
